DESCRIPTION
The BL6528 is a low cost, high accuracy, high stability, electrical energy measurement IC intended to single phase, multifunction applications.
The BL6528 incorporates two high accuracy Sigma-Delta ADC, voltage reference, power management and digital signal processing circuit using to calculates active energy , reactive energy ,apparent energy ,IRMS ,VRMS etc.
The BL6528 measures line voltage, current and calculates active ,reactive ,apparent energy, power factor, line frequency, detect SAG, overvoltage, overcurrent, PEAK, zero-crossing voltage.
The BL6528 provide access to on-chip meter registers via SPI munication interface. The BL6528 provide all-digital domain offset pensation, gain adjustment, phase pensation (maximum ±2.54°adjustable).
